The utility model is reasonable in structural design, the opening range of the magnetic disk is increased, and the maximum lifting length can be more than 20 meters.
Description
The utility model relates to a kind of disk hanging beam, belongs to hoisting crane magnetic load erecting by overhang, is specially adapted to lift by crane various steel billets, beam-and-rail and the shaped steel of big cut lengths.
Disk hanging beam of the prior art mainly is made up of hanging beam body, assembly pulley, disk drive and disk.The hanging beam body adopts the welding process identical with bridging crane main beam usually, causes it to have a certain amount of camber.Disk drive is mainly by cantilevered decelerator, chain wheel driving mechanism, square thread traveling screw mandrel and nut engaged and disk is mobile trolley used forms with it.Disk by chain sling be installed in disk mobile trolley used below.The cantilevered decelerator drives square thread traveling screw mandrel and rotates through chain wheel driving mechanism, and to traveling, the mobile trolley used drive of driving disk is contained in the disk folding below it to nut along screw axis.It is 15 meters that existing magnetic disc suspending Liangqi disk aperture scope is generally the maximum lifting of 3000mm～7500mm length.But development along with rolling technique, require the cut lengths of lifting constantly to increase, this just requires to increase the aperture of disk, also be the length of hanging beam body, and two groups of movable pulleys between square can not increase by the restriction of monkey lateral dimension, can only increase the length of hanging beam two ends cantilever, when lifting, just make hanging beam produce sizable camber like this, it will be superimposed with the original camber of hanging beam, make the hanging beam can't normal operation, thereby limited the increase of lifting by crane length, to the development formation obstruction of rolling technique.In addition, the cantilevered decelerator that the disk mobile device is adopted, though have little, the lightweight advantage of volume, when being subjected to impact shock, the cantilever flange portion is easily broken, influence is produced and is normally carried out.Square thread traveling screw mandrel, accuracy of manufacture requires high, the root of the tooth weak strength, bad to neutrality, to install and change inconvenience, screw thread pair wearing and tearing post gap is difficult to compensation and repairs, the maintenance cost height, and the disk aperture is not frequently adjusted, the advantage that square thread screw mandrel driving efficiency is high also can't be given full play to.
The utility model purpose provide a kind of rational in infrastructure, the lifting length range is big, reliable operation, manufacturing, installation, maintenance is convenient, maintenance cost is low disk hanging beam.
The purpose of this utility model realizes by following measure.
The hanging beam body has the following amount of deflection of δ=0～10 millimeter, the camber that the hanging beam body is produced.Through the transmission of elastic coupling drive speed reducer, the drive sprocket of chain wheel driving mechanism is installed on the output shaft of reductor disk drive by electrical motor.The traveling screw mandrel is an Acme thread traveling screw mandrel, and nut engaged is the dissection type nut with it.
The advantage that the utility model is compared with prior art had is: 1. the hanging beam body has following amount of deflection, and reasonable in design helps the increase that hanging beam length also is the disk aperture, and its maximum lifting length can surpass 20m, has satisfied the needs of rolling technique development.2. in the disk mobile device, adopt electrical motor, elastic coupling and reductor to replace former cantilevered decelerator, solved the problem that former decelerator cantilever flange often breaks and damages, improved functional reliability.3. Acme thread traveling screw mandrel, tooth root intensity height, good to neutrality, to make, installation, maintenance is convenient, adopts the dissection type nut to cooperate with it, is easy to adjust and eliminate the gap, service expenditure is low.
Below in conjunction with accompanying drawing embodiment of the present utility model is discussed in detail.
Accompanying drawing is the structural representation of the utility model disk hanging beam.
As shown in the figure, the utility model disk hanging beam mainly is made up of hanging beam body 1, lifting sliding guide 2, assembly pulley 3, disk drive 4, endless chain 13, disk 14 and middle auxiliary suspension hook 17.Hanging beam body 1 adopts the operation opposite with traditional handicraft on welding process, welded lower cover and web earlier, and then welding upper cover plate and web, utilizes welding interior stress poor, makes it produce the following amount of deflection of δ=8mm.Two disk drives 4 that are contained in hanging beam body 1 both sides mainly are made up of the dissection type nut 12 and the disk mobile trolley used 11 of electrical motor 5, rubbercushioned sleeve bearing coupling 6, cycloidal planetary gear speed reducer 7, chain wheel driving mechanism 8, Acme thread traveling screw mandrel 10 and cooperation with it.Disk drive 4 by electrical motor 5 through 7 transmissions of rubbercushioned sleeve bearing coupling 6 drive speed reducer.Acme thread traveling screw mandrel 10 is supported on the hanging beam body 1 by the bearing installation at its two ends.The outer end of Acme thread traveling screw mandrel 10 also is that the driving end bearing is the spherical outside surface rolling bearing 9 of usheing to seat, can compensate installation error voluntarily, be convenient to regulate, non-transmision end is the integrated structure of single-row radial ball bearing 15 and double-direction thrust ball bearing 16, to adapt to the axial force that Acme thread traveling screw mandrel 10 is produced in transmission process.The drive sprocket of chain wheel driving mechanism 8 is installed on the output shaft of cycloidal planetary gear speed reducer 7, is installed in the outer end of traveling screw mandrel 10 by movable sprocket.Disk mobile trolley used 11 is connected with dissection type nut 12, and disk 14 is lifted on the below of disk mobile trolley used 11 by endless chain 13.
The whole magnetic disk hanging beam is lifted on by lifting wire rope on the dolly of crane in bridge type by assembly pulley 3, and the driver train on the dolly drives the lifting of disk hanging beam through steel cable and assembly pulley 3.Lifting sliding guide 2 matches with guide groove on the monkey, avoids the swing significantly in the course of the work of disk hanging beam.Electrical motor 5 drives cycloid through rubbercushioned sleeve bearing coupling 6 and really takes turns reductor 7, the mouth of reductor 7 drives 10 rotations of Acme thread traveling screw mandrel through chain wheel driving mechanism 8, the dissection type nut 12 that matches with traveling screw mandrel 10 drives disk mobile trolley used 11 and axially moves relatively or contrarily along screw mandrel 10, makes to be lifted on the length folding of following disk 14 according to hanging object.The auxiliary suspension hook 17 in centre that is contained in hanging beam body 1 middle part generally only uses when maintenance.
In-place test shows, adopting the utility model design-calculated disk aperture is the disk hanging beam of 3～20 meters of 3000mm～9500mm, lifting length, at disk maximum opening 9500mm, 20 meters of lifting steel billet length, under the situation that load is 20.8 tons, the hanging beam body produces the affix amount of deflection of 6～9mm, with the original 8mm design of hanging beam body camber basic neutralisation, the disk hanging beam works well, and meets the requirement of Rolling Production fully.
